[@rollup/plugin-dynamic-import-vars] Allow path.relative

[rtritto]

• Rollup Plugin Name: @rollup/plugin-dynamic-import-vars
• Rollup Plugin Version: 2.1.5

Feature Use Case

Load API routes using filesystem.

Feature Proposal

Ignore path.relative:

• as parameter

  import fs from 'node:fs'
  import path from 'node:path'
  
  const files = fs.globSync(pattern, { cwd: entryDir })
  for (const file of sortRoutesByParams(files)) {
    // Fix Windows slashes
    const filepath = file.replaceAll('\\', '/')
    await import(path.relative(entryDir, filepath))
    // ...
  }

• as resolved

  import fs from 'node:fs'
  import path from 'node:path'
  
  const files = fs.globSync(pattern, { cwd: entryDir })
  for (const file of sortRoutesByParams(files)) {
    // Fix Windows slashes
    const filepath = file.replaceAll('\\', '/')
    const resolved = path.relative(entryDir, filepath)
    await import(resolved)
    // ...
  }

Current

VariableDynamicImportError: invalid import "import(path.relative(entryDir, filepath))". It cannot be statically analyzed. Variable dynamic imports must start with ./ and be limited to a specific directory. For example: import(`./foo/${bar}.js`).
